SD-WAN security: The impact of orchestrated services multiplicity

In tandem with the deployment of 5G networks is the emergence of edge computing and edge clouds – placing data processing and storage in close proximity to where it’s needed on the enterprise edge. Moving computing closer to the enterprise edge improves network performance and reduces cost as traffic no longer needs to be routed to central clouds. 5G networks and edge computing are creating new business opportunities and richer consumer experiences. Many mobile service providers are planning to shift their network delivery from a few mega-capacity central clouds to thousands of edge clouds that support more agile, customizable services. Without integration, the new 5G network edges are where the new security challenges will likely occur. The performance of 5G networks has to be matched by the associated security and computing components. Without strategic security planning, the necessary security solutions could inadvertently create bottlenecks that negate the value of edge computing. Enabling applications to perform at 5G speeds to ensure expected user experience is one thing, but ensuring that this happens securely, across more network access points than ever before, presents an entirely new set of very serious challenges. Organizations need to be prepared today with stronger, broader, integrated and automated security foundations.

The RAN (Radio Access Network) architecture for mobile networks includes a remote radio unit (RRU) located at the top of a cell tower, which communicates with a baseband unit (BBU) at the base of the tower. The hardware and communication interfaces are owned by a specific vendor, and its software-driven functionality is tightly coupled within the hardware. Traditionally, this has worked well for mobile network operators (MNOs). However, there are several drawbacks to consider – for instance, upgrading or changing the wireless network demands physical hardware replacements throughout the network, which is cost-inefficient, labor-intensive, and time-consuming. Furthermore, the equipment and interfaces that connect the hardware are owned by the vendors that originally supplied them, which locks MNOs into existing relationships with them.

The next-generation of wireless technologies – known as 5G – is here. Not only is it expected to offer network speeds that are up to 100 times faster than 4G LTE and reduce latency to nearly zero, it will allow networks to handle 100 times the number of connected devices, revolutionizing business and consumer connectivity and enabling the “Internet of Things.” Leading policymakers – federal regulators and legislators – are making it a top priority to ensure that the wireless industry has the tools it needs to maintain U.S. leadership in commercial 5G deployments. This blog provides monthly updates on FCC actions and Congressional efforts to win the race to 5G.

Despite the COVID-induced interruptions in the first half of 2020, 5G preparations and deployment continued in earnest in the second half of 2020 and now the market – vendors, CSPS, OEMs – are ready to bring 5G to the masses of users. The arrival of Apple’s first 5G devices in 4Q20 marked the tipping point of global consumer readiness, now extending from early-adopters. After the initial phase of network launches that saw coverage built-out in major urban centres, 5G service providers should now focus on expanding coverage to as many areas of high-data demand as possible. At the same time, as CSPs gauge their 5G roll-out strategies, they shouldn’t ignore rural areas with limited-to-no high-speed broadband coverage. In many markets, particularly developing ones, CSPs should carefully assess network-sharing as a way to cost-effectively tap pent-up demand, especially given the accelerating remote working trend.
